The "Notices" clause in the contract is one of the key elements of the contract that provides clarity and legal certainty in formal communications between the parties. The article specifies the various ways in which notices may be delivered (by mail, e-mail, fax and courier) and when and under what conditions a notice is deemed to have been delivered to the receiving party. A properly organized system of notices facilitates the proper performance of the parties' obligations under the contract, proper timing, the recording of facts and evidence, and the preparation of a documentary basis for possible defense in court.
